Morphological control of MAPbI(3) crystal growth is one of the most important factor to fabricate high efficient perovskite solar cells. Herein, different boronic acid derivative self-assemble monolayers were used for modification of c-TiO2 surface and controlling of interface properties between c-TiO2 and MAPbI(3) layers. Pre-mixed MAPbI(3) solution in GBL was deposited by spin-coating technique onto non-modified and modified c-TiO2 surfaces by selected SAMs. The 1-OMe modified c-TiO2 based solar cell shows an increase in J(sc), resulting an increase to 9.4% PCE to compare with 5.9% PCE of non-modified c-TiO2 based solar cell. With this work, we demonstrated the possibility of morphological control of perovskite layer by using simple modification method of sublayer to increase the photovoltaic characteristics of solar cells.
